• The words AND, OR and NOT may confuse the search; try adding quotes: "%christian ((union conversations) or (win conversations)) %((2f germany) or (2 germany)) %2f history %2f ((20th century) OR (18th century))%22".
• Adding a wildcard symbol may retrieve word variants: %christian ((union conversations) or (win conversations)) %((2f germany) or (2 germany)) %2f history %2f ((20th century) OR (18th century))%22*.
